Advancements in Endoscopic Techniques for Early Detection of Gastric Cancer

Abstract

Gastric cancer (GC) remains one of the most common and deadly cancers globally. Early

detection is critical in improving survival rates, yet current diagnostic methods often miss

asymptomatic or early-stage tumors. Over the last decade, significant advancements in

endoscopic techniques have revolutionized the approach to detecting gastric cancer in its

early stages. This paper examines the latest innovations in endoscopy, including high-

definition endoscopy, magnifying endoscopy, narrow-band imaging (NBI), and artificial

intelligence (AI)-integrated systems, highlighting their efficacy in identifying precancerous

lesions and early-stage gastric tumors. The review also discusses the challenges and

limitations in implementing these technologies universally and their potential future

applications.
